Design Statement The purpose of this project is to design and build a new front-suspension for Sunsation II.

Prior Design

Improvements Weight Adjustable Wheel Scrub Ride height Braking assembly Shock selection

Design Specification Easy Adjustment; camber, caster, toe-in/out Mounting to honeycomb unibody 6” of total shock travel Little weight Support body weight (= lb)

Budget Bulk metal (aluminum/iron) Shocks Wheels Tires Hardware (Bolts/Nuts) Steering linkage Steering Box Brake calipers Brake rotors Rotor hubs Brake lines Master cylinder Pedal Assembly Total

Tasks Completed WBS Schedule (primavera) Budget Final Design Shock specifications Designing Bulk Head Simulated Drawings Fine tuning suspension geometry to minimize scrub

On-Going Task Modeling components in Pro-E/Working model 2-D Ordering parts/materials Suspension Calculations

Uncompleted Tasks Connecting Suspension All finalized engineering drawings Machining parts Analyzing Performance Stress testing of suspension Suspension performance

Team Improvement Better organization of work time Total group involvement

Next Semester Task Analyzing material stress/strain Material Selection Ordering parts Machining and assembly Analyzing Performance Stress testing of suspension Suspension Calculations Incorporation of Stirring System

Conclusion Though the project is behind schedule for most groups on the solar car. We do hope to accomplish our over all goals that were set from the start. This has also been a stressful but simulating learning experience.
